Patent GB-364400-A (GB)
Title: Improvements relating to the manufacture of synthetic resins
IPC: C08F8/12
Filed: 1931-02-19
Abstract: Synthetic resins are manufactured by causing a polymerized vinyl chloracetate to react with an alkali compound of an organic acid, phenol or alcohol, in the presence of a non-reactive solvent in which the polyvinyl chloracetate is soluble, preferably an acetic ester. The products are substantially free from chlorine and are useful for the manufacture of protective finishes or as constituents of moulding compositions.  In examples, polymerized vinyl chloracetate is treated with: (1) sodium butyl phthalate (obtained by reacting equimolecular proportions of n-butyl alcohol and phthalic anhydride in toluene solution and treating the product with caustic soda), at 150 DEG  C. in the presence of the acetate of ethylene glycol monoethyl ether; (2) sodium ethyl phthalate, using the same solvent and refluxing the mixture; (3) sodium acetate in the presence of n-butyl acetate, under reflux; (4) the sodium salts of linseed oil acids, under the same conditions as in (3); (5) potassium phenoxide, under the same conditions as in (2).  Other alkali compounds specified as suitable for the reaction are: alkali salts of aromatic acids, sodium alcoholates, such as sodium glycerylate, and monoand disodium salts of dibasic acids (the last-named being, however, less suitable). Salts of esters of dibasic acids other than phthalic acid may also be employed.  Cyclohexyl acetate is also specified as a solvent.

An engine 2, Fig. 1, is mounted in an enclosed compartment 5 at the nose of fuselage 1 and is cooled by air entering at 6, 6, Fig. 4, the cooling air on passing the engine being directed by a bulkhead 7 into an exhaust pipe 9 streamlined into the fuselage contour. Engine exhaust pipes 12, Fig. 2, are combined to form manifolds 13 discharging by nozzles 13a into conduits 15 which 'at their after ends are blended into exhaust pipe 9 and at their forward ends receive air from openings 11, Fig. 4, formed with scooplike mouths 14, Fig. 2. This arrangement is stated to have an extractor effect on the exhaust gases. The pipe 9 may run along the top of the body or one pipe may be fitted at each side, in each case discharge is at the tail of the aircraft. In a modification, the engine cooling air is not led into exhaust pipe 9 but is guided into a channel 16, Fig. 3, and pipe 9 is formed with fins 17. In a further modification, the manifolds are disposed in lateral recesses in the body constituting the mouths of conduits 20, Fig. 7, extending along the sides of the fuselage and discharging at outlets 21 formed in a trailing part of the fuselage either above (as shown) or below the rudder. Pressureoperated emergency release valves may be provided in the exhaust pipes, these valves being normally maintained shut by springs, weights or by the action of the relative wind. In the case of water-cooled engine installations, the cooling air exhausted from the engine compartment through pipe 9 may be arranged first to pass through an enclosed radiator. The exhaust pipes may be lagged with heat-insulating material when they arc juxtaposed to the fuselage or nacelle. Air or exhaust gases or a mixture of the two may be led from pipe 9 into pipes or passages 25, Fig. 7, running along the leading edges of the wing and discharging at the wing tips.

Title: Computer interrupt circuit
IPC: H03K3/45
Filed: 1967-02-08
Abstract: 1,146,112. Computer interrupt circuitry. WESTINGHOUSE ELECTRIC CORP. 8 Feb., 1967 [1 March, 1966], No. 6053/67. Heading G4A. [Also in Division H3] Computer interrupt circuit for transferring information into a magnetic core simultaneously with a probe pulse voltage from a probe circuit, comprises a set of winding on the core, a threshold switch operative to switch on upon a predetermined voltage difference thereon, said threshold switch being connected in series with the set winding, an input circuit for supplying the input information in the form of an input voltage, a charge accumulating circuit responsive to the input voltage for creating a minimum voltage level, the accumulating voltage being in series with the winding and the threshold switch, wherein means is provided for isolating the probe pulse voltage from the threshold switch until the minimum voltage level has been reached. Peripheral devices such as typewriters, card or tape readers, tape punches or analogue input systems actuate an input circuit 14 as shown (or a relay switch, not shown) to render the transistor non-conducting and apply a voltage to input junction 62. When the voltage across a storage capacitor reaches a predetermined value sufficient to produce a set current pulse in coil 26 a Zener diode 80 becomes conductive and causes a transistor 75 to be rendered conductive. This completes the loop 64 including the secondary of the transformer 70. At the first coincidence of a probe voltage pulse with the predetermined voltage level at junction 62 the threshold switch 66, preferably a four-layer solid state device, is caused to breakover and a current sufficient to set the core flows. After set current switch off when low current and voltage conditions cause switch 66 to reset the accumulated back voltage across a blocking capacitor 74 prevents the potential at junction 82 from reaching the breakover level of the Zener diode so the transistor 75 is held non- conductive to isolate the probe pulse from the threshold switch. When the interrupt drive voltage is removed from the junction 62 the blocking capacitor discharges via circuit 14, diode 86 and Zener diode 80. When the core is set a pulse is produced at HIT terminals to set a flip-flop to which several of the cores are connected. The computer then interrogates the cores in a predetermined order to determine which units produced interrupts and in which order they should be serviced. An interrupt circuit according to the prior art is described (Fig. 1, not shown) which does not include the isolating transistor.

Abstract: 797,910. Angular bending. CHAMBERLAIN INDUSTRIES, Ltd. Feb. 20, 1957 [Feb. 27, 1956], No. 6081/56. Class 83 (4). A machine for bending rods or tubes having a rotary forming die to which the work is secured and about which the work is bent upon actuation of the die by an hydraulic fluid actuator, has valve means which stops the rotation of the forming die when the work has been bent through a predetermined angle and means to indicate the angle of bend. A spindle 26 is adjusted about its axis, by a cap 33, until a pointer 36 therein indicates on a fixed scale 37 the angle to which the work is to be bent, the spindle 26, by virtue of a one-way helical clutch spring 39, turning relative to a coaxial hollow shaft 31. A lever 10 is then actuated to rock a crank 14 linked to the stem 7 of a spool-type valve 6 in the supply line from the hydraulic power source to driving means for the forming die. The forming die, with the work clamped thereto, then rotates to bend the work and through chain-and-sprocket means drives the shaft 31 and, through the helical spring 39, the spindle 26 at twice the speed of the die. Rotation continues until a member 23 projecting from the spindle 26 hits a rocking cam 19, of inverted T shape, to depress the valve spindle 7 and close the valve 6 to stop the bending. The member 23 could alternatively engage a switch contact to make or break the circuit of a relay or solenoid operating the valve. Similar levers 10 may operate the clamp which secures the leading end of the work to the forming die, a pressure die, a mandrel and a booster.

Abstract: 1456728 Pile fabrics W HURTES 11 Feb 1974 [12 Feb 1973] 06102/74 Heading D1K A pile fabric is produced by adhesively attaching tufts to a backing surface by cutting pile lengths from a series of cylinders of compressed fibres, transferring them by vacuum means to a driven belt or surface on which they expand laterally to a predetermined density and then attaching them to an adhesively coated backing layer.  As shown in Fig. 1 fibres 25 are wrapped in a film 24 and the two are compressed in a funnel 31 and the film sealed by rollers 34. The cylinders so formed are fed in to holders on a conveyor belt and cut into lengths by a band saw 43 which moves towards the holders to produce a straight cut. The cylinders are moved forward from the holders 12 and cut again into pile lengths by a blade 67 and passed to transfer means 93 which have walls 86, 87 and are provided in their bases by suction means to hold the pile units in place. The film surrounding each pile unit is then out by blades 94 and drawn off by rollers 95, 96. The pile density is then sensed and the pile expanded by air or live steam at 19. A backing layer 20 is then applied to the thus expanded tufts. In an alternative embodiment, Fig. 8, the transfer mechanism is replaced by a porous belt 160 and vacuum chest 163. Various diverging restraining members and fluidised bed type means are provided in alternative embodiments to expand the pile.
